Chainsaw Sharpening Vise: Stump Vise vs Bench Vise, and Why the Bar Has to Stay Still

A stump vise and a bench vise both get called a chainsaw sharpening vise. One is a spike driven into a log in the field. The other bolts to a workbench and needs soft jaws first.

They are not interchangeable, and picking the wrong one means fighting your saw every time you file. A field crew does not want to haul a bench vise to a job site. A shop that sharpens chains once a week does not need a spike driven into a stump.

This page sorts out which chainsaw sharpening vise fits your situation. It covers what branded options add over generic ones. It also covers how a bar mounted file guide pairs with either setup.

What a Chainsaw Sharpening Vise Has to Do

Filing a chain by hand takes two hands. One holds the file, the other holds the guide against the cutter. If the bar can rock while you work, your angle drifts from cutter to cutter.

A chainsaw sharpening vise solves this by locking the bar in place. That frees both hands and keeps the same angle stroke after stroke. It also stops the chain from creeping under file pressure.

None of this requires a powered sharpener. It just requires the bar to hold still. That keeps your cutter count and depth gauge spacing consistent too.

Stump Vise: The Field Setup

A stump vise is a small clamp with steel forks on one end. You drive the forks into a stump or a log, then lock the bar in the jaw above them. The chain stays on the bar the whole time you file.

Oregon’s own listing for its 26368A model matches this design. Forks drive into any stump and the jaw locks the bar securely. The company lists it at under one pound, light enough to carry all day.

Retailers sell the same part under a few names: filing vise, stump vise, chain vise. It is one design with one job. A chainsaw stump vise is the closest thing this category has to a standard tool.

Branded versions from Oregon, Stihl, and Husqvarna sit alongside plenty of generic ones. Generics claim to fit every major saw brand and work fine for occasional use. Heavier duty versions from Forester and Tecomec’s chain stop model aim at people who sharpen chains for a living.

Bench Vise With Soft Jaws: The Shop Setup

A standard bench vise can hold a chainsaw bar too. Bare steel jaws can mar the rails or pinch them if you crank down hard. Most shop setups add something soft between the bar and the jaws first.

A common fix among owners is a scrap wood cradle: two blocks cut to grip the bar. It takes about five minutes with hand tools you already own. Some owners glue magnets to the blocks so they grip the jaws on their own.

A short length of aluminum angle cut to jaw width works the same way and holds up longer.

Not everyone bothers. One owner says he has clamped bars straight into bare steel for years and calls it standard practice. Others will not risk it, since a marred rail can bind the chain later.

Log Vise and No Vise Workarounds

A log vise is really the same idea as a stump vise, just clamped to a fallen log instead of a standing stump. Anyone cutting firewood in the field already has the log; the vise just needs somewhere to bite.

Plenty of people skip a vise entirely and file with the saw on the ground, on a tailgate, or braced against a knee. It works, but it is also the most common reason chains pull to one side after filing. Without something holding the bar still, your angle changes every few strokes without you noticing.

Shop owners with long bars sometimes solve the space problem by clamping a stump vise into a bench vise instead of buying a second tool. It gets you a portable field vise and a stable shop mount from one purchase.

Pairing a Vise With a Bar Mounted File Guide

A vise and a file guide solve two different halves of the same problem. The vise keeps the bar from moving. A guide like the Granberg G-106B keeps the file itself at a fixed angle, since holding a file steady by eye is where most hand filed chains go wrong.

Skip it if all you want is a bar holder. Buy a stump vise for that and save the money. It suits owners who already have a way to hold the bar and want repeatable angles without a powered grinder.

Which Setup Fits Your Situation

Field pros and anyone who fells or bucks away from a shop want a stump vise in the saw box, full stop. It is light, cheap, and does its one job without complaint.

Weekend firewood cutters can go either way. A generic stump vise costs less than a tank of gas and covers occasional use fine. If you already have a bench vise at home, a wood cradle costs nothing but ten minutes.

Shop only sharpening, especially with several saws or long bars coming through, favors a bench vise with soft jaws or aluminum angle stock cut once and reused. A chain stop model adds real value here if chain creep during filing has been a recurring headache.

Frequently Asked Questions

Do I need a chainsaw sharpening vise, or can I just file on the ground?

You can file without one, but the bar will shift slightly with every stroke. That shows up later as a chain that pulls to one side.

Is a stump vise the same as a bench vise?

No. A stump vise has forks that drive into wood and is built for the field. A bench vise bolts to a workbench and needs soft jaws added before it can hold a bar safely.

Can I clamp a chainsaw bar directly in a bare steel bench vise?

Some owners do this for years without trouble. Others avoid it because bare steel jaws can mar or pinch the bar rails over time. A wood or aluminum liner removes the risk either way.

Are generic stump vises as good as Oregon or Stihl branded ones?

For occasional use, most owners report generics work fine. Branded and heavy duty versions add sturdier castings and, in Tecomec’s case, a chain stop feature aimed at daily professional filing.

Does a bar mounted file guide replace a vise?

No. A guide like the Granberg G-106B clamps to the bar and controls file angle, but the bar still needs a vise or another stable mount underneath it.

What is the cheapest way to hold a chainsaw bar for filing?

A scrap wood cradle sized to your bar and set in an existing bench vise costs nothing but a few minutes with a saw.

Holding the bar still is one half of a consistent hand filed edge. For the other half, getting your file diameter right matters just as much as keeping the bar from moving, and looking up your chain’s exact fit settles that before you buy anything. Once the bar is locked down, the file angle and stroke count breakdown covers the actual filing motion stroke by stroke.
